扭绞线

Integrated welding equipment in the strander is co-ordinated with the welding and bobbin loading operations.

集成在扭绞机内的焊接设备与焊接和线轴装载操作步调一致，和谐工作。

IMF Impianti will be presenting the new generation skip strander of unique design for automatic loading of 7 bobbins in less than 5 minutes.

IMF Impianti公司将展出其新一代设计独特的级跳式扭绞机，它可以在不到5分钟的时间内自动装载7个线轴。

This assay is focuses on part of access network technology. The main contents are as the follows.To discuss the function of the forthcoming copper loop, city cable channels once and twice parameters are analyzed and calculated, and simple analytic model are used to describe the characteristics of channel. The transformation of parameter related to applied HDSL technology in higher band of frequency, and the influences of near reaction and twisted subscriber line are mainly analyzed.

本文针对接入网技术的部分技术进行了分析和讨论，主要内容有以下几部分：为探讨现有的铜线回路的性能，对市话电缆信道的一次参数和二次参数进行了分析计算，并引入简单的解析模型来描述信道特性，其中着重分析了与应用HDSL技术有关的较高频段内参数的变化，邻近效应和用户线扭绞等因素的影响。

When connectors are attached to the ends of UTP cable, the wire pairs should be untwisted as little as possible to ensure reliable LAN communications.

当接头是附在UTP缆线端点时，这对线未被扭绞的部分应尽可能少，以确保可靠的LAN通讯。
